Author: Vincent
Favre-Nicolin, in collaboration with Radovan
Cerny.
The program was written at the Laboratory
of Crystallography, in Geneva (Switzerland), with support from the
Swiss
National Science Foundation. (project #21-53847.98)) The SpaceGroup/element
library used in FOX was made by R. Grosse-Kunsleve (follow this link
if you are interested). See the ObjCryst++
homepage for more details.
NEWS
Latest version is 1.0 (15 oct 2001). It adds support for multi-phase powder patterns, allows importing data from sietronics (.cpi) data format, and correct some bugs (incorrect interpretation of Z-Matrix geometry, crashing when importing data with null or negative points). See the changelog.Introduction
The FOX program was mainly made for the Global Optimization of Crystal Structures from powder diffraction data. i.e. if you :DownloadThen FOX can help you.
- have an unknown compound but with (approximately) known composition.
- have a powder pattern (X-Ray or Neutron or both), which you have already indexed (with the refined unit cell), and for which you have some idea of the possible spacegroup(s) (using systametic extinctions).
- would like to know where the atoms are.
This program can be used also for educational purposes, to show a 3D display of Crystal structures, and the associated powder pattern(s) (see how adding atoms, changing the lattice, or changing the spacegroup affects the powder spectrum and the 3D structure).
If you would also like to choose your own criterion and algorithm to solve the structure, then it will be even better : FOX is built on a very customizable and expandable library, which allows you to evaluate your Crystal structure following a combination of criteria: currently there are only R, Rw factors and an Anti-bump cost funtcion, but it would be very easy to write a new criterion using (say) interatomic distances (energy of the configuration, analysis of the coordination). This is what makes this program different from other available programs.For example currently you can combine several Powder patterns (X-Ray, Neutron,...) for the same structure,...
FOX is available in precompiled form for Windows (98, NT) and Linux-x86 (the source code is available along the ObjCryst++ code-see the ObjCryst++ home page for info). You can download from several sites: For Windows, download the Fox-Windows-20011015.zip file.InstallationFor Linux, download the Fox-Linux-x86-20011015-glibc21.tar.gz or Fox-Linux-x86-20011015-glibc22.tar.gz file, depending on the glibc version (2.1 or 2.2) version that you have on your computer. If you cannot resolve dependencies problems, contact me to compile Fox from source (or see the ObjCryst++ home page).
Note1: This is a young version
of
both
the program and the documentation. So if you have remarks about
what could be done to significantly improve the program (or the documentation),
feel free to send me an
email, especially if something on this page does not work
The program is currently not very forgiving for improper or unexpected
input (hence follow closely the above step-by-step howto).
Note2: This is an open-source project. If there is something that you would like to see in it, you can contribute to it by submiting code. See the ObjCryst++/FOX Web Site for details.
Note3: if the program encounters an error, it will sometime
try to save the complete environment in a file which should be in the Fox
directory, named "ObjCryst-date-time.xml" , which you can reload.
